PHOTOUTHO WASHINGTON u c "E STATES PATENT EMIL FRUEI-I, OF CEDAR RAPIDS, IOWA.

SPECIFICATION forming part of Letters Patent No. 611,408, dated September 27, 1898.

Application filed Novembe 4, 1897. Serial No, 657.354. (No model.)

To all whom it may concern.-

Be it known that I, EMIL FRUEH, a citizen of the United States,residing at Cedar Rapids, in the county of Linn and State of Iowa,have invented a certain new and useful Improvement in Orozing or Grooving Tools for Barrels and the Like, of which the following is a specification.

My invention relates to a new and useful improvement in crozing or grooving tools for barrels and the like, and has for its object to provide a simple, cheap, and effective device of this description which may be adjusted to staves of various curves and by means of which a groove may be quickly cut for the reception of the wedge-shaped ends of the head. 7 A

With these ends in view this invention consists in the details of construction and combination of elements hereinafterset forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, its construction and operation will now be described in detail,referring to the accompanying drawings, forming a part of this specification, in which--- Figure 1 is a side view of my improved tool, showing it in active position within a barrel, forming the groove therein; Fig. 2, an edge view of the tool, the adjustable follower-wheel being in section; Fig. 3, a slight modification showing my improvement adapted for holding two tools; Fig. 4, a cross-section of afurther modification, illustrating the method of utilizing two blades for cutting one groove; and Fig. 5, a detail of a method of adjusting the follower-wheel by a sliding holder.

In carrying out my invention as here embodied, A represents the frame of the tool, one edge of which is curved to approximate with the contour of the barrel to be operated upon, and in a slot formed in the front end of this frame is journaled the leader-roll 13, whose periphery is ofa shape adapted to fit the groove to be formed. A slot is also formed in the rear portion of the frame and has secured therein an eccentric washer O by means of the screw-pin D, and this washer is held in a number of adjustments by a set-screw E, passing through a threaded hole in the frame and entering one of a series of slots F, as will be readily understood. Upon this washer is j ourn aled the follower-wheel G, the periphery of which is similar to that of the roll B, and the object of this roll and wheel is to guide the tool in its operations in form- 1 By the use of a tool made in accordance with my improvement it will be seen that a groove may be quickly out near the ends of the staves for the reception of the head, and the depth of this groove may be regulated by the adjustment of the tool, and also when said tool becomes dulled it may be sharpened by grindingthe face thereof and resetting within the frame. j

The curvature of the barrel is compensated for by the adjustment of the trailer-wheel, as before described, and this, taken in connection with the adjustment of the groovingcutter, will permit this tool to accomplish work upon a variety of sizes and shapes of barrels.

The letter X indicates bolts on which a suitable gage may be secured in order that the distance at which the groove is out from the rim of the barrel is regulated.

In Fig. 3 a slight modification is shown in which two tools M and N are utilized, and said tools are held in a swinging housing 0, which is made adjustable by means of the screw P, by which arrangement the depth of the tools may be varied, and this modification is adapted for operation upon work which requires formation of the groove to take place gradually.

In Fig. l two blades Q, are provided and set at an angle, where they are clamped by means of the block B, so that the proper adjustment of these blades will form a complete cutter and have a V-shaped groove, as will be readily understood.

The trailer-wheel S in Fig. 5 may be journaled in an adjustable holder T, which is secured to the frame by the screw U, and thus the adjustment of this wheel may be accomplished without the use of an eccentric 7 washer, as above set forth.

Having thus fully described myinvention, what I claim as new and useful is- I 1. In a grooving-tool, a frame formed of a single piece of metal curved longitudinally and slotted centrally and at each end, a leaderadjustable blade arranged in said central slot, as and for the purpose described.

2. In a grooving-tool, a frame formed of a single piece of metal curved longitudinally and slotted at each end, a leader-roll journaled in one end, a spindle extending across the slot at the rear end an eccentric bushing journaled thereon, a disk formed on the bushing a screw threaded through one side of the frame into one of a number of holes in the sides of said disk, and a trailer-wheel journaled on said bushing, as and. for the purpose described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
